Description

Technical Field

[0001] The utility model relates to rubber preparation, in particular to a waste gas treatment device for silicone rubber preparation, belonging to the technical field of rubber preparation. Background Art

[0002] Silicone rubber processing plants are mainly used to produce silicone rubber products, which usually include kneading (mixing), open mixing, feeding, extrusion molding, calendering molding, vulcanization, crushing and processing. These production processes will generate waste gas or dust. Therefore, waste gas treatment is required to meet the emission standards. The existing waste gas treatment measures usually collect the generated waste gas through the gas collection hood, and then send it to the water spray tower through the air duct for pretreatment through the gravity provided by the fan. After further cleaning and treatment in the water spray tower, it enters the secondary activated carbon adsorber for adsorption treatment. The activated carbon adsorber adsorbs the mixing waste gas, and after the treatment meets the standards, it is discharged at high altitude through the air duct.

[0003] However, the air collecting hood used in the above system cannot adjust the height of the hood plate. The closer the air collecting hood is to the exhaust gas source, the better the air collecting effect can be. The air collecting hood that cannot adjust the hood plate has very high requirements on the accuracy of installation height and different exhaust gas sources require the design of mounting frames of different heights, which makes the installation of the air collecting hood extremely cumbersome. In addition, the activated carbon plate in the activated carbon adsorber is inconvenient to install and disassemble, which is not conducive to maintenance work. Therefore, in view of the above problems, a waste gas treatment device prepared by silicone rubber is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a waste gas treatment device made of silicone rubber. The rubber can adjust the height of the air collecting hood cover plate so that the air collecting hood can produce the best air collecting effect on the waste gas source. At the same time, there is no requirement for the installation accuracy of the air collecting hood, which can improve the construction efficiency, and can still be adapted to different waste gas sources by adjusting the height of the cover plate. In addition, a number of plug-in activated carbon plates are provided in the activated carbon adsorber, which can facilitate maintenance work, solving the technical problems in the prior art that the height of the air collecting hood cover plate makes installation and use inconvenient and the maintenance and replacement operations of the activated carbon adsorber are relatively cumbersome.

[0005] In order to solve the above problems, the following technical solutions are provided:

[0006] A waste gas treatment device for the preparation of silicone rubber is designed, comprising a movable gas collecting hood, a spray tower, a plug-in activated carbon adsorber and an exhaust fan, the above four being connected in sequence through an air pipe, the movable gas collecting hood comprising a hood base, a first package plate being fixedly arranged on the left and right sides of the hood base, a second package plate being fixedly arranged on the front and back sides of the hood base, a movable cover plate made of metal whose inner wall is in close contact with the first package plate and the second package plate is provided on the outer sliding sleeve of the hood base, an electromagnet is embedded in the middle of the first package plate and the second package plate, and the outer end face of the electromagnet is flush with the outer side faces of the first package plate and the second package plate.

[0007] The above-mentioned structural form collects the exhaust gas through the movable gas collecting hood, and then treats the exhaust gas through the spray tower and the plug-in plate type activated carbon adsorber. In this process, since the movable cover plate is movably mounted on the outside of the cover base, the cover plate height can be changed by sliding the movable cover plate when the cover base is fixed, thereby achieving a better gas collection effect. During adjustment, the electromagnet is in a power-off and stopped working state. At this time, the friction force on the movable cover plate is small, and the height can be adjusted. After the height adjustment is completed, the electromagnet is energized to generate an adsorption force on the movable cover plate. At this time, the movable cover plate is fixed by greater friction. In addition, the plug-in plate type activated carbon adsorber can facilitate the replacement of the internal activated carbon structure, which is convenient for maintenance and replacement.

[0008] Furthermore, the first package plate has limit slide grooves on both sides of the outer end surface, and the movable cover plate has limit slide bars fixedly arranged on the inner walls on both sides, and the limit slide bars are stuck in the limit slide grooves and slidably arranged in the limit slide grooves.

[0009] The above-mentioned structural form can realize a reliable sliding connection between the movable cover plate and the cover base by means of the limiting slide bar being stuck in the limiting slide groove and slidingly arranged therein, ensuring that the movable cover plate can only move straight up and down during the sliding process.

[0010] Furthermore, auxiliary slide grooves are provided on the left and right sides of the outer end surface of the second package plate, and auxiliary slide bars are fixedly provided on the inner walls of the front and rear sides of the movable cover plate, and the auxiliary slide bars are slidably provided in the auxiliary slide grooves.

[0011] The above-mentioned structural form can realize a reliable sliding connection between the movable cover plate and the cover base by slidingly setting the auxiliary slide bar in the auxiliary slide groove, ensuring that the movable cover plate can only move straight up and down during the sliding process.

[0012] Furthermore, the plug-in plate type activated carbon adsorber comprises a box body, in which a plurality of groups of slot plates arranged transversely are fixedly provided, and a movable plug-in plate is slidably plugged into the slot plate.

[0013] In the above structure, since the movable plug board is slidably plugged into the slot board, when the movable plug board needs to be maintained or replaced, it can be directly taken out by pulling it out, and can be directly inserted during subsequent installation, which can greatly improve the work efficiency during maintenance and replacement.

[0014] Furthermore, the movable plug plate comprises a metal frame, a through placement groove is provided in the middle of the metal frame, and an activated carbon plate is placed in the placement groove.

[0015] In the above structural form, the activated carbon plate is directly placed in the metal frame. When the activated carbon plate fails or has poor effect, the metal frame can be pulled out and the activated carbon plate placed therein can be replaced, which can significantly improve work efficiency.

[0016] Furthermore, a sealing plate is fixedly connected to the outer end of the metal frame, and a sealing gasket is fixedly attached to the inner wall of the sealing plate.

[0017] In the above structure, after being fully inserted into the metal frame, the sealing plate can squeeze the sealing gasket to make it in close contact with the outer wall of the box body, thereby preventing leakage of exhaust gas.

[0018] Furthermore, a socket is provided on the front plate of the box body, the position of which corresponds to the setting position of the slot plate, and the opening size of the socket is consistent with the outer cross-sectional size of the metal frame.

[0019] The above structural form provides the necessary structural basis for the plugging and unplugging of the movable plug board as a whole.

[0020] Furthermore, a connecting pipe is fixedly connected to the top of the cover base, and a section of the connecting pipe away from the cover base is tightly connected to the air pipe.

[0021] The above structural form can realize a sealed connection between the mask base and the trachea.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] In the utility model, the exhaust gas is collected by a movable gas collecting hood, and then treated by a spray tower and a plug-in plate type activated carbon adsorber. In this process, since the movable cover plate is movably sleeved on the outside of the cover base, the cover plate height can be changed by sliding the movable cover plate when the cover base is fixed, thereby achieving a better gas collection effect. After the height adjustment is completed, the electromagnet is energized to generate an adsorption force on the movable cover plate, and the movable cover plate is fixed by greater friction. In addition, the plug-in plate type activated carbon adsorber can facilitate the replacement of the internal activated carbon structure, thereby facilitating maintenance and replacement.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

In the above structural form, the waste gas is collected by the movable gas collecting hood 1, and then the waste gas is treated through the spray tower 2 and the plug-in plate type activated carbon adsorber 3, wherein the plug-in plate type activated carbon adsorber 3 can facilitate the replacement of the internal activated carbon structure, and thus facilitate maintenance and renewal.

[0033] like Figure 2As shown, the movable air collecting hood 1 includes a hood base 11, a first package plate 12 is fixedly provided on the left and right sides of the hood base 11, a second package plate 13 is fixedly provided on the front and rear sides of the hood base 11, and a movable cover plate 14 made of metal whose inner wall is in close contact with the first package plate 12 and the second package plate 13 is slidably sleeved outside the hood base 11, and an electromagnet 15 is embedded in the middle of the first package plate 12 and the second package plate 13, and the outer end surface of the electromagnet 15 is flush with the outer side surfaces of the first package plate 12 and the second package plate 13. Since the movable cover plate 14 is movably sleeved outside the hood base 11, the height of the cover plate can be changed by sliding the movable cover plate 14 when the hood base 11 is fixed, thereby achieving a better air collecting effect. During adjustment, the electromagnet 15 is in a state of power-off and stopping work. At this time, the friction force on the movable cover plate 14 is small, and the height can be adjusted. When the height adjustment is completed, the electromagnet 15 is energized to generate an adsorption force on the movable cover plate 14, and the movable cover plate 14 is fixed by greater friction.

[0034] like Figure 2-3 As shown, limiting slide grooves 121 are provided on the left and right sides of the outer end surface of the first package plate 12, and limiting slide bars 141 are fixedly arranged on the inner walls on the left and right sides of the movable cover plate 14. The limiting slide bars 141 are stuck in the limiting slide grooves 121 and are slidably set in the limiting slide grooves 121. The above-mentioned structural form can realize a reliable sliding connection between the movable cover plate 14 and the cover base 11 in a manner in which the limiting slide bars 141 are stuck in the limiting slide grooves 121 and are slidably set therein, thereby ensuring that the movable cover plate 14 can only go straight up and down during the sliding process.

[0035] like Figure 2-3 As shown, auxiliary slide grooves 131 are opened on the left and right sides of the outer end surface of the second package plate 13, and auxiliary slide bars 142 are fixedly arranged on the inner walls on the front and rear sides of the movable cover plate 14. The auxiliary slide bars 142 are slidably arranged in the auxiliary slide grooves 131. The above-mentioned structural form can realize a reliable sliding connection between the movable cover plate 14 and the cover base 11 in the manner that the auxiliary slide bars 142 are slidably arranged in the auxiliary slide grooves 131, thereby ensuring that the movable cover plate 14 can only go straight up and down during the sliding process.

[0036] like Figure 4 As shown, the plug-in plate type activated carbon adsorber 3 includes a box body 31, in which a plurality of groups of transversely arranged slot plates 32 are fixedly provided, and a movable plug plate 33 is slidably inserted in the slot plate 32. Since the movable plug plate 33 is slidably inserted in the slot plate 32, when the movable plug plate 33 needs to be maintained or replaced, it can be directly taken out by pulling it out, and can be directly inserted during subsequent installation, which can greatly improve the work efficiency during maintenance and replacement.

[0037] like Figure 5As shown, the movable plug plate 33 includes a metal frame 331, a through placement groove 332 is opened in the middle of the metal frame 331, and an activated carbon plate 333 is placed in the placement groove 332. In the above structural form, the activated carbon plate 333 is directly placed in the metal frame 331, and the metal frame 331 can be pulled out after the activated carbon plate 333 fails or has poor effect, and the activated carbon plate 333 placed therein can be replaced, which can significantly improve work efficiency. In addition, a sealing plate 334 is fixedly connected to the outer end of the metal frame 331, and a sealed gasket 335 is fixedly attached to the inner wall of the sealing plate 334. After being fully inserted into the metal frame 331, the sealing plate 334 can squeeze the sealed gasket 335 to make it in close contact with the outer wall of the box body 31, thereby avoiding leakage of exhaust gas.

[0038] like Figure 4 As shown, a socket 34 is provided on the front plate of the box body 31, and the position thereof corresponds to the setting position of the slot plate 32. The opening size of the socket 34 is consistent with the outer cross-sectional size of the metal frame 331. The above-mentioned structural form provides the necessary structural basis for the overall insertion and removal of the movable plug plate 33.

[0039] like Figure 2 As shown, a connecting pipe 16 is fixedly connected to the top of the cover base 11 , and a section of the connecting pipe 16 away from the cover base 11 is tightly connected to the air pipe 5 . The above structure can achieve a tight connection between the cover base 11 and the air pipe 5 .

[0040] The use principle and use process of the utility model: the device as a whole is composed of a movable gas collecting hood 1, a spray tower 2, a plug-in plate type activated carbon adsorber 3 and an exhaust fan 4. The above four are connected in sequence through an air pipe 5. The exhaust gas is collected through the movable gas collecting hood 1, and then the exhaust gas is treated through the spray tower 2 and the plug-in plate type activated carbon adsorber 3.

[0041] At the same time, since the movable cover plate 14 is movably mounted on the outside of the cover base 11, the cover plate height can be changed by sliding the movable cover plate 14 when the cover base 11 is fixed, thereby achieving a better air collection effect. During adjustment, the electromagnet 15 is in a power-off and stopped working state. At this time, the friction force on the movable cover plate 14 is small, and the height can be adjusted. After the height adjustment is completed, the electromagnet 15 is powered on to generate an adsorption force on the movable cover plate 14. At this time, the movable cover plate 14 is subjected to greater friction and is fixed.

[0042] In addition, since the movable plug plate 33 is slidably inserted in the slot plate 32, when the movable plug plate 33 needs maintenance or replacement, it can be directly taken out by pulling it out, and can be directly inserted during subsequent installation, which can greatly improve the work efficiency during maintenance and replacement. Among them, the activated carbon plate 333 is directly placed in the metal frame 331. After the activated carbon plate 333 fails or the effect is poor, the metal frame 331 can be pulled out, and the activated carbon plate 333 placed therein can be replaced, which can significantly improve the work efficiency.
